SPST switch mb8719 pins 11 & 12 to each other
SPST switch mb8719 pin 10 to ground
SPST switch mb8719 pin 9 to IC side of cut trace at pin 14

the 9 to 14 switch gets you .415-.445 on 37-40.

you'll need a road map, and a freq counter is a nice addition, but final coverage will be 26.815-28.085, completely. add 10kc switch, and slide mod of at least 5kc to get every single freq in there.
